I am replacing my windshield divider. My replacement part lacks the predrilled holes of the original. I have a Master Deluxe model, do I need these holes? How critical is the distance between the top and bottom of the divider where it is welded in place. Can I be too high or too low in locating the divider? Any pointers are appreciated. Nice to learn from you guys rather than from the school of hard knocks! The pictures show my concerns.




SEE the predrilled holes at the top and bottom of the divider


Since the part seems to be prone to rust I think I will sandblast it and put a coat of Por-15 on it? Also what center rubber pieces will I need to purchase for the Master Deluxe set up. Chev's of the 40's lists a Windshield Center Rubber Division with holes (part # 4122594B) and also the complete Windshield Rubber for windshields without molding (part # 4116250E). I assume I do not need the rubber channel for holding the exterior center molding?

Thanks, Mike

This is an update of my original post with followup questions. I am pre-fitting my windshield rubber pieces that I purchased from Steele. The following pictures I hope will explain what sequence I need to follow to install the glass, rubber seals, and stainless divider. Please remember I have a Master Deluxe so do not need to deal with the stainless surrounding the windshield.

My overall intent is to follow the installation directions in my 41 body manual, and the advice from previous posts. My first concern is how to reattach the stainless on my center windshield divider. Do I need to glue the rubber shown in the 2nd picture in place? I think I could get the stainless to fit over it by screwing in the inside center garnish piece to hold the rubber while I install the stainless? Could I wait until I have the glass all installed and then put the stainless on? This is contrary to the advice provided in the 46-47 shop manual as stated in the 4th picture. My interest in doing the stainless last is so I could put extra sealer in the top and bottom areas which might be prone to water leaks? Can anyone explain the pros and cons of this?

My ultimate goal will be to post additional advice to make this a job a lot of us can feel comfortable doing ourselves.


My new, metal, vertical windshield divider.


The rubber for holding the stainless in place. I think I cut it too short so will stretch it. Or should I not worry how short the center seal channel is at the top and bottom?[/b]


This shows the back of the the rubber piece used for mounting the stainless.


Advice provided in the 46-47 shop manual.


Stainless trim resting on rubber sealing channel.


Rubber window weatherstrip resting on pinch weld to determine overall fit.




Overall fit at top and bottom of center divide before stretching rubber. I don't know how easy it is to align the stainless then later work the ends of the large weather seal under the stainless? Notice how short the rubber vertical divider is. Did I cut too much off? I could stretch it?



Thanks, Mike

Did you receive a instruction sheet from Steele with the rubber? Also, what products did you buy to install, sealers, etc.? Steele also has very good tech support as they do this type work at there location. I called and talked to them before I started. Nice folks!

Hi Russell,

The Steele directions do recommend sealers, but their were no directions on installing the center windshield rubber divide channel. I appreciate your recommendation to give them a call.

Thanks, Mike

P.S. Hoping to hear from Latigo. Anyone know if he is up yet?

Mike, I have done two, a 1940 Special Deluxe and a 1948 Fleetmaster. Both had the stainless trim so the rubbers were slightly different than your Master which has the lip that goes over the pinch weld. I don't remember whether or not my division bars had the holes you mention, but can see no reason why they are necessary. Maybe they were just to locate the originals at the factory. As far as the up/down position of the bar itself goes, the only thing that does is locate the inside division bar cover that holds the rear view mirror. Since there are little covers for each end I think you probably have a little leeway there. My old division bar was still in place so I took an accurate measurement of the old one before cutting it out, and located the new one in the same location. Regarding your question about the length of the division bar rubber: The main purpose of this rubber is to secure the stainless verticle trim piece. I think it should hold the trim in place even if it is a little short. The question is, will it leak water? The fact that almost every one of these cars has a rusted out division bar shows there is obviously some water leakage into this area even if installed perfectly. Now, with a little gap at the ends, will this allow water to flow through at a rate that will allow it to leak inside onto the dash? I don't know. Maybe it will just run in at the top and right back out at the bottom, and cause no problem. Stretching it might work, but it might just shrink back into its original length over time. My own feeling is that this is such a pain in the axx job I would not want to have to redo it. I think I would rather have the center rubber a little too long, put some sealer on it, and scrunch it up into place where it might have a better chance of sealing. If water gets between the rubber and stainless trim it wont hurt anything, but you don't want water to collect between the rubber and the division bar itself. Your idea to POR will probably help, but the original division bars were painted at the same time as the car body, and still rusted out over time.

iagree With everything. One thing to remember, the strip is two pieces of metal and the crimps to captive the nuts. Their is no way to completely cover between the two pieces or under the bends or the nuts. The slightest moisture in and, rust starts.

I finished my installation about a month ago but have procrastinated on updating you with my results. I did install the stainless after successfully installing the front glass and did it with the engine and front sheetmetal off the car. It is much easier to muscle the stainless in place with out straddling the engine/hood/fenders. I also was helped a lot by the above post of Latigo's.

Most of the pictures show green tape on my division stainless. I spent several hours wet sanding the stainless and then buffing it so I used the tape to protect my work. I also was careful to use some thick electrical tape to protect my paint job at the top and bottom of the window opening where the stainless can easily scratch the paint. You also want to use padding to cover the top of the firewall where you might drop a tool.

Make sure you check the width of your stainless if you are replacing it with another new piece or have welded in a new division piece. My 41 stainless piece was wider than one I had taken off of a 47.

It is not easy to get the stainlees over the rubber that holds it in place. To cheat a little I trimmed a little off of each end so that the rubber did not quite fit over the metal division piece about an inch from the top and bottom. When I was ready to start I put a heavy coat of straight Baby Shampoo on the rubber. Next I worked the right side of the stainless into its rubber groove. I started at the top and worked down. Even this was a challenge to make sure you get the stainless seated the entire length of the rubber groove. Now reapply your soap to the left side and begin pushing the stainless to the left and the groove it fits in. I found I was not strong enough to work the stainless in place so beginning at the top I used an old feeler gauge and slide it under the top of the stainless on the left side, about 3 inches from the top. I could now push the stainless more easily into the groove. I then moved my gauge about 2-4 more inches down and pushed more of the stainless in place. I continued the routine until I had worked all the stainless into the groove.

Try to concentrate on pushing the stainless to the left and not straight down. Pushing it down may bend the center division piece so the glass/weatherstrip fits poorly.

With the stainless in place rinse the soap from the rubber and after a few days apply sealer at the top and bottom under the stainless.















Good luck, Mike

I should also mention that I used a small thin bladed putty knife (1") to massage irregularities between the stainless and rubber groove. Mostly I was just pushing into the rubber groove to get the stainless to seat better. If you are worried about scratching the stainless put a piece of painter's tape over the blade of the putty knife.

I would not install the interior division metal strip (the part that holds the mirror) until you have finished mounting the stainless and then I would not tighten the screws. Let everything shift gradually into its natural place. In fact compressing the rubber components would make it harder to work the stainless into its groove. You should however have prefit everything to check the length of the stainless screws, and see if the screw holes all lineup and thread properly. Chevs of the 40's sells the proper stainless screws. The screws are a little shorter, and the heads are a little larger than those found at your local ACE Hardware.

Thanks, Mike

P.S. I would not be in a hurry to tighten the garnish on your front or rear windows. Maybe even wait until your car has set in the sun or been driven a little. It could be kind of like wearing too small of a belt?

I have kind of talked myself out of reinstalling my sunvisor after finishing my installation of the stainless vertical divide. My main concern is how the Fulton would be attached to the stainless. I just do not think the stainless would hold up to the pressure of holding down the sunvisor. As you can see in my picture a bolt was used to hold the stainless to the inside garnish. I am reluctant to drill a hole through my new stainless to keep it from popping off when the car is driven! I would strongly recommend that if you are going to attach a visor to the stainless you put a bolt through it attaching it to the inside garnish. If you are hesitant to do that then be careful to monitor the condition of the stainless. Any sign of it lifting out of the channel holding it should be a warning of bad things to come.

Hi Mike, the winter is gone and now its time to keep going. And here is my first question, how did you weld your divider. Did you drill holes and then weld it together with zhe window frame? Mine doesn' fix at the moment. Should i cut out the little peace at the top too? Pictures will follow

Hi Andre,

My best advice is to try to get the new piece to be even with the window opening. If you align it to fit inside the window opening you end up with the surfaces too far apart for the rubber to mat well. Looking carefully at your old welded area you will see it is about 1/16 to 1/32 of an inch behind the window opening. The replacement piece is two pieces of metal. I would cut the thin outer piece about 1/2" off at the top and bottom so it aligns with the outed edge of the window opening. Then I would remove all the old center piece on the inside at the top and bottom. Then weld the new piece in as tightly as possible to the inside of the window opening. It will make a big difference if you are not careful and end up with the center divide not even with the outside surface of the window opening.

My mistake was having the entire center divide welded on the inside of my window. Causing about 1/8th of an inch of difference in the outer surface of my window and the center divide. This made for a real challenge for me when I installed my glass and stainless trim.

Best wishes,
Mike

P.S. I have the entire exterior of my car finished and am now working on the interior. We have had a mild winter so hope to test drive the car at the end of the month.

For the top one think you are right and i have to cut the outer one, but the bottom i should´t cut. But it must come closer to the frame. You can see it on the pictures. I put some old pictures into the album
